Accurate circuit modeling of fishnet structures for negative-index-medium applications
(IEEE, 2016) Artículo / Artikulua,
Metallic plates with a two-dimensional (2D) periodic distribution of sub-wavelength apertures are known to exhibit extraordinary transmission of electromagnetic waves. Stacking two or more of such plates gives place to the ...
Epsilon-near-zero metalenses operating in the visible
(Elsevier, 2016) Artículo / Artikulua,
Several converging lenses working in the permittivity near to zero (ENZ) regime at optical frequencies are designed using an array of metal-dielectric-metal plasmonic waveguides. These plasmonic waveguides show a dispersive ...
Hedgehog subwavelength hole arrays: control over the THz enhanced transmission
(Institute of Physics Publishing, 2013) Artículo / Artikulua,
By backing or sandwiching a holey metal layer with or between isotropic dielectric slabs, additional peaks of transmission within the long-wavelength regime arise as a result of the induced transverse magnetic (TM) or ...
A slow light fishnet-like absorber in the millimeter-wave range
(EMW Publishing, 2011) Artículo / Artikulua,
A novel route to achieve a narrowband free-space electromagnetic absorber in any range of the spectrum based on stacked subwavelength hole arrays is proposed. The absorption is obtained by means of a slow light mode inside ...
Lensing system and Fourier transformation using epsilon-near-zero metamaterials
(American Physical Society, 2012) info:eu-repo/semantics/article,
Metamaterials and metastructures with effective relative permittivity near zero exhibit unusual wave properties such as uniform phase distributions across such domains. Here we discuss the possibility of using ε-near-zero ...
